Tanzanite gets its name from Tanzania, the country where it is found. This remarkable gemstone was discovered in 1967 and named by Tiffany & Co. Tanzanite has a mesmerizing blend of rich purples and blues with a velvety deepness of color unlike any other gem. Depending on how it is viewed, tanzanite often changes color from a sapphire blue to violet to burgundy. As the birthstone of December, tanzanite jewelry is a delightful gift for new mothers and those born in December.
